In Class I occlusion, the mesiobuccal cusp of the maxillary first permanent molar should align with the buccal groove of the mandibular first permanent molar. As Angie's teeth meet in this alignment, her occlusion falls in Class I. This is considered a normal occlusion. Class II, division I and Class II, division II occlusions involve a malalignment of the upper and lower jaws, while Class III occlusion involves the lower jaw protruding out in front of the upper jaw.
